Compute all parts of given question:

Question: A spherical shell is formed by taking a solid sphere of radius 25.0cm and hollowing out a spherical section from the shell's interior. Assume the hollow section and the sphere itself have the same center location (that is, they are concentric).

Part A: If the hollow section takes up 90.0 percent of the total volume, what is its radius?

Part B: What is the ratio of the outer area to the inner area of the shell?

I need help to find the ratio of the outer area to the inner area of the shell.
